0 Li-ion/Li Polymer Battery Charger The ISL9203 is an integrated single-cell Li-ion or Li-polymer battery charger capable of operating with an input voltage as low as 2.
4V.
This charger is designed to work with various types of ac adapters.
The ISL9203 operates as a linear charger when the ac adapter is a voltage source.
The battery is charged in a CC/CV (constant current/constant voltage) profile.
The charge current is programmable with an external resistor up to 1.
5A.
The ISL9203 can also work with a current-limited adapter to minimize the thermal dissipation, in which case the ISL9203 combines the benefits of both a linea...
